Last reviewed 10/2022

The majority of leiomyomas arise in the body of the uterus and are described according to their anatomic location:

  • intramural - 70%
  • subserous - 10%
  • submucosal - 10%

Less commonly, they arise in the cervix, between the leaves of the broad ligaments, and in the various supporting ligaments of the uterus.

A newer and more detailed leiomyoma subclassification system has been introduced by the International Federation of Gynecology and Obstetrics (FIGO) (1).
